三角洲

Delta plain divided distributary river course and between river courses.

三角洲相区分为三角洲平原、三角洲前缘和前三角洲三个亚相。

The deposital system was composed of three whole deposital association including delta plain, the front of delta and frontal delta.

其中该三角洲体系由三角洲平原、三角洲前缘和前三角洲三个完整的沉积组合构成。

In this thesis, beginning with the research of the Yellow River delta formation history, the landscape heterogeneity is related with the delta evolution. According to different dynamic environments, the Yellow River delta landscape is divided into three zones: delta plain landscape, tidal zone landscape and submerged delta landscape, and the landscape characters of each zone is analyzed and discussed respectively.

本文从黄河三角洲的形成和发育研究入手，将黄河三角洲的形成与演化与景观分异联系起来，根据动力因素的差异提出黄河三角洲景观的三带结构，即：陆上三角洲景观、潮间带景观和水下景观，就三个带的景观特征分别进行了比较深入的分析和探讨。

Delta, the main types of fan-shaped delta, a bird-shaped feet and pointed Delta Delta.

三角洲的主要类型有扇形三角洲、鸟足形三角洲和尖形三角洲。

The deltas differ from typical deltaic model.Deltaic front subaqueous distributary channel sand bodies and deltaic plain distributary channel sand bodies are the skeleton sand bodies of meandering stream-shallow sea delta and braided streain-shallow lake delta respectively but not tranditional deltaic front river mouth sand bars.

这两类三角洲与经典的三角洲模式不同的是，三角洲前缘水下分流河道砂体和三角洲平原分流河道砂体分别构成了曲流河浅水海相三角洲和网状河浅水湖泊三角洲的骨架砂体，而不是传统认为的三角洲前缘河口砂坝。

Through fully digested available information and predecessor's cognition, using whisht and dynamic data acquisitied from each stage, making a refined known and interpretation for single reservoir sand, construct, collector, sediment etc in the oilfield. By dint of numerical reservoir simulation and producting history fitting for verification and adjustion.

通过现代沉积类比，在对取心井、大量电测资料和沉积微相研究的基础上，认为五2西克下组属于扇三角洲沉积体系，纵、横向上相变快，造成储层非均质性强。S_7~(42)为扇三角洲上分流平原亚相沉积；S_7~(41)为扇三角洲下分流平原亚相沉积；S_7~3扇三角洲内前缘亚相沉积；S_7~2、S_7~1均为扇三角洲外前缘亚相沉积。

ABSTRACT The Yellow River delta located in the land and sea interaction zone and is being formed with the coaction of the River and Bohai sea. The three parts of the whole delta, i. e. the delta plain, tidal zone and submerged delta, are in different dynamic environments. The delta plain is controlled by the land surface processes. The tidal zone is under the coaction of the river and the sea.

黄河三角洲处于海陆交错地带，是河流与海洋因素共同作用的堆积体，从陆上三角洲平原到潮间带直至水下三角洲受不同动力因素的作用，陆上三角洲平原主要受陆地表层过程的影响；潮间带受陆、海动力的共同作用，而水下三角洲主要受海洋动力的作用。

The Es formation was divided into seven third order sequences based on the seismic, drilling and logging data, and plans deposition system plane distribution maps of different time were plotted by dominance phase principle. The lower Es4 is flood-overlake facies mainly; the upper Es4 is meandering stream and braided river delta deposition above the shore shallow lake background; in the Es3 period, the south mainly developed braided river, meandering stream delta, the northeast area main developed meandering stream delta, the middle area mainly developed semi-deep lakean d deep lake sediments. From lower Es3 to upper Es3, the delta scale gradually increased and the depositional area gradually moved to the east and the southeast; the Es2 period was dominated by shore-shallow lake sediments and widely developed braided river delta and delta deposits; the Es1 period was dominated by shore-shallow lake shoal deposits, and in the south developed meandering stream and braided river delta deposits.The lothological traps of the Shahejie group are mainly fluxoturbidite and stratum lateral pinch-out, and its formation and the distribution of the lothological trap were controlled mainly by the basin structure characteristic, palaeogeomorphology and tectonic activity and so on. It had a beneficial geological condition to develope sublacustrine slump turbidite fans in Jishan, Jiangjiadian and Wawu.

利用地震、钻井、测井等资料，将古近系沙河街组划分出7个三级层序，通过剖面沉积学分析，以优势相原则绘制不同时期各亚段沉积体系平面分布图：沙四下总体以洪水-漫湖沉积为特征，沙四上沉积时期是在滨浅湖背景之上发育了曲流河三角洲和辫状河三角洲沉积；沙三段沉积时期南部主要发育辫状河、曲流河三角洲，西北部地区发育曲流河三角洲，中部地区主要为深湖—半深湖沉积；由沙三下至沙三上，西北部三角洲规模逐渐增大，沉积范围逐渐向东、东南方向推进；沙二段沉积时期为滨浅湖沉积，在背景之上广泛发育了辫状河三角洲和三角洲沉积；沙一段以滨浅湖滩坝沉积为特征，南部发育了曲流河三角洲和辫状河三角洲沉积；沉积地层中的岩性圈闭以滑塌浊积岩岩性圈闭和地层侧向尖灭型岩性圈闭为主，其形成和分布主要受盆地结构、沉积古地貌和构造活动强度等因素控制，北部基山、南部江家店和瓦屋具有发育滑塌浊积扇的良好地质条件。

For example, we are planning上东三角洲agents on exactly at the Beijing Lufthansa, Wangjing, Lido three major shopping district of the Upper East Wai All New "heart" area; while the other Nancheng星河城project, then close fit Nancheng Beijing the pace of the rise of these two projects are related to the formation of regional development into the interactive posture, and are more than millions of square meters large.

例如，我们正计划上东三角洲代理人恰好在北京燕莎，望京，丽都三大购物区东围上所有的新&心脏&地区；而其他南城星河城项目，然后关闭适合北京南城的速度上升，这两个项目都涉及到区域发展形成的互动状态，并有超过百万平方米大。

During the paleo-geography evolution, inland lacustrine basin began to form, and the two delta skirt in east and west lakeshore are primary formed in Chang 10, lacustrine basin subsidized quickly, lake district enlarged rapidly and destructive delta are developed in Chang 9, delta are more developed in Chang 8, lakeshore line move outward at large range, turbidite developed well near west lakeshore, delta range is decreased in east lakeshore in Chang 7, features of lacustrine basin are changed remarkably, deep lake and half deep lake area is decreased greatly, while delta sedimentary system is developed at its most in Chang 6, framewok is inherited better, but delta′s construction is slowed and is swamping at large scale in Chang 4+5, lacustrine basin began to be silting, shrinking and dying out, and riverway gradually developed well since Chang 3, distributary riverway developed best in Chang 2, because of imbalance subsidence, subsidence center is formed in east Zichang area and in which lacustrine turbidite is sedimented.

在古地理演化过程中，长10期内陆湖盆开始形成，东西两岸两大三角洲裙初步形成；长9期湖盆快速下沉，湖区迅速扩大，三角洲多为破坏性的；长8期三角洲进一步发育；长7期湖岸线大幅度向外推移，西部浊积岩发育，东部三角洲面积明显减小；长6期湖盆面貌发生了显著的变化，深湖－半深湖面积大大减少，三角洲沉积体系极为发育；长4+5期继承了长6的沉积格局，三角洲建设进程减慢，三角洲大面积沼泽化；从长3期湖盆开始逐步淤浅、萎缩、消亡，河道逐渐发育；长2期分流河道发育；长1期由于差异沉降，在东部子长一带形成沉降中心，沉积了湖相浊积岩。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
